Is it correct to write: Small change makes a big difference or do I need an indefinite article a at the beginning of the sentence? Why?
1 Answer
I would use one of the following two sentences:
A small change makes a big difference.
Small changes make a big difference.
In other words, with an "a" I'd frame it in the singular—because you're talking about a single small change; otherwise, in the plural—because you're talking about small changes in general.
Here, I'm thinking of change meaning "the act, process, or result of changing."
The only way I can make sense of "small change" without an "a" being put in the singular is when I think of change meaning "coins especially of low denominations · a pocketful of change."
With that meaning, then it makes sense to say:
Small change makes a big difference (when it comes to tipping your server).
And here, small change is being treated as a collective singular, in the same way that an uncountable noun would be.
I believe this answer (aside from the specific final example) will apply to any other countable noun. For instance, you would treat smart idea in the same manner.
However, it would not apply to uncountable nouns. Water, always in the singular without something additional (like body of), would never take "a" front of it.
As one comment validly pointed out, you can order "a water" (or "a coffee") at a restaurant. But, in that case, I would argue that you are using an uncountable noun as if it were countable. (And, in terms of meaning, assuming that the missing "bottle of," "glass of," or "cup of" is understood.)

3It's odd that the original sentence could actually pass if it excluded small. Great explanation.– AdamCommented Jun 19, 2018 at 8:36

2Yeah, this covers the entire question completely (incl. 'small change' referring to money), to the point where there's nothing left for others to write. The only improvement I could suggest is the obiter dictum on 'water' is too strong. 'A water' certainly exists in certain contexts, particularly ordering at restaurants; many uncountable words can be countable when used to discuss one instance or one kind of the stuff.– llyCommented Jun 19, 2018 at 13:15

I believe the original meaning of the phrase is in reference to coins. It might be said in a conversation like so: Bob - "Hey! There's a penny!" Tom - "Meh, not worth it to pick up such small change." Bob - "Small change makes a big difference." (Bob picks up the penny). Commented Jun 19, 2018 at 13:51

I would argue that "Small change makes a big difference" in the sense of the act of changing is still valid, in the same sense that you could say "Change is coming", rather than "A change is coming"– MayubeCommented Jun 19, 2018 at 16:37

1@Mayube If you strongly believe that, you could write up a separate answer, but it would get downvoted because it's wrong. Like Mr Bassford already said, 'change' can be an uncountable abstract idea or countable instance of change; changes can be small but there is no abstract idea of 'small change', only a mass noun for 'too many small coins to bother counting'.– llyCommented Jun 20, 2018 at 2:44
